Hi guys,
I need some help with these two problems. I think i got them right, but I would need someone to confirm that I am correct.
Thx a lot!
2.1  I think the circuit is valid. When I go around the circuit in the direction of the current there is a 40 volt voltage rise, then a 10 volt drop and a 50 volt drop. So across the current source there is a 20 volt voltage rise. The power delivered is 300 watts, and the power absorbed is also 300 watts.
2.3  I think this interconnection is also valid. Going around the circuit in the direction of the current there is a 20 volt voltage drop, then a 15 volt voltage rise, so across the current source there has to be a 5 volt rise.
b. 20 volt source absorbs power
15 volt source develops power
5 amp source develops power
c. Power absorbed is 100 watts.
Power developed is 100 watts
d. The circuit is invalid because there is only voltage rise in the circuit.
